[Where I give you advice like I know what I'm talking about]

Seven small things that are easy to do and easy on your wallet.

1) (for those who menstruate) Use a menstrual cup.  No garbage, no plastic waste, no chemically treated cotton inside of you, nothing to remember to buy/have around each month except one discreet little cup!  This of course doesn't work for everyone, but for some people it can be a FANTASTIC solution.  It's a one time cost, but lasts for something like 10 years. 

2) Make your own salad dressing.  Some kind of oil, some kind of vinegar, some kind of sweetening, mustard.  Anything on top of that is icing on the cake!  Or spice in the dressing, as it were...

3)  Use vinegar for cleaning and disinfecting.

4) Water it down! 

5) If you eat meat, use less.  I'm not talking full on vegetarianism here (though that's cool if you want to), just cut it back a bit.  Say, halve the amount of meat you add into a recipe and double the veg.  Or take days off from meat.

6) Stop eating junk food.  Or cut it down.  Junk food is expensive and wasteful and never tastes as good as you want it to and makes you feel a bit icky afterward (or should I say, ME).  Of course, nothing beats a good burger, but at least find a GOOD burger.  Something that will be worth it to you.

7) Switch paper for cloth.  Bags, kleenex, towels, wipes, heck, some people even do it with toilet paper!  (A non-threatening way to do this is to just use cloth for #1...)

What other kinds of things do you do to save around the house?
